Today is the last day of my Easter holidays and I managed to complete my skin.
Today is the bug fixing day so I ask everyone to please download my skin to test it and report me any bugs they find. You can DOWNLOAD IT HERE

I also need help with two things that I just couldn't figure out how to remove the white border around task pane and the white gaps between progress bar chunks. Any help would be much appreciated. Please se pics below for reference.

As V already said above, yes you can lose the gap on the progress bar, adjust the margin settings. And if need be, make another graphic for it to suit your needs. Look at some other skins to get the idea.

The single-pixel white border around the shellstyle panel will go away if you designate a Task Pane image in XP Shell/Task Pane. For some reason, just setting background color(s) leaves that single pixel border white.
